It ships as a 4-unit pack and is designed for the 3VA6 150/250 frame breakers. Strip length is 0.7 in (about 18 mm). The terminal carries UL/CSA marking 14-1/0 CU9 TC1.3 CMC UR CSA and IEC marking 1.5-50 mm² CU NNL, so it's accepted in both North American and European panel builds. Lifecycle status is current/active per Siemens — this is not a phase-out or NRND line item. It's a standard accessory for the SENTRON 3VA molded-case breaker family, so it moves as a BOM-consistent spare rather than a specialty oddment. For a panel builder or MRO planner, this means the 3VA9144-0JK11 is a straight replacement for any 3VA6 150/250 installation that needs the circular terminal with tap-off. No last-time-buy clock ticking. ## Wire range and fit Solid copper: 14 AWG min, 10 AWG max. Stranded and finely stranded: 14 AWG min, 1/0 AWG max. That covers most panel power and control wiring from a #14 control circuit up to a 1/0 feeder tap. The control wire voltage tap-off is the feature that saves a separate splice block — one less connection point in the panel, one less thing to torque-check during commissioning.","metaTitle":"Siemens 3VA9144-0JK11 SENTRON Accessory, Circular Conductor","metaDescription":"Siemens 3VA9144-0JK11 SENTRON circular conductor terminal accessory.
